To @ZZ whom, it may concern: l

Be it known that I, ZEPHANIAH SANFORD f LAWRENCE, aV subject of the Kingof Great Britain, and a resident of Westl SheHord, in the .Province ofQuebec and Dominion of Canada, have invented a new and Im roved StorageandCooling Vat for Milkv or ream,

.of which the following is a full, clear, and

therebetween through which -a coohng medium is adapted to-be passed. Ashaft con- 2 5; centrically journaled in the vat isl operable tov drivea 'paddle\adjustably fixed thereto, and also carries a` series'ofradiating, dischargi pipes for delivering and distributing the mil orcream in the vat adjacent to the inner cooling wall. This deliveryisenforced through the p'pes by the action of the centrifugal i force asthe pipes revolve. V

Reference is to be had to the accompanying drawings forming a part ofthis specifica- 3 5 tion, in whichlsimilar characters of referencelndicate corresponding parts in all the figures.

tion Jconsists of an upright, cylindrical vatA constructedof sheet metaland having-an `outer andan inner wall with a spiral passage `v'ention,and' 2 is a transverse, sectional Patented June 18, 1907.

l spirally arranged-a wall 8 formin a'spiral passage com municgtin at.its perip ery with a spiral passage forme by the wall-9.inter mediatethe outer andinner walls 1 and 4 of the vatrespect1vely.- Leading to thes iral passage between the double .bottom o the vat at its center,-is apipe 10 for the purpose of conducting spring, well water, or `othercooling medium to said spiral. assages, which discharge'itthrough anover owpipe 11 connecting with the upper. assage b etween the walls 1and '4., It 1s a parent from this construction that the coolingl medium,on entering the pipe '10,' will be caused to travel spirally through thelbase of the vat, as also between-the sidewalls before being`discharged, thereby; affording time for the walls of the vat toapproachthe temperature' .of the cooling medium before the atter'isejected.

Journaled in crossbars 12 and 13', res ectively arranged at the to andbottom'o vthe vat, 1s a central shaft 14, i aving a radial arm 15 fixednear itslower end. 1 `Also'fixed to the shaft adjacent to the crossbar12 is acup 16 having a perforated bottom, each perforation' with one ofa series of radiaty ing pipes 17, preferably-formed integral withcommumcating 'the cup. f

Adjustably suspended from one of the pipes 17 is a rod 18 adaptedto beheld 1n lined position vby the set-screw` shown', and

carrying at its '.lower'end'a paddle 19 pro--v vided atene face/with aneye which' is engaged by the arm 15 `causing the paddle to revolveas'the shaft 1.4 is rotated- For rotating the shaft-a pulley 21 isfixed. to its upper extremity, lwhich is drivenby a belt 22- from anysuitable source ofpower. lIn the operation of the vat, the Imlllr orcream is conducted through its u pper end by a pipe o r trough 23dschargmg mto the c up 16, which' lfeeds it through the v radiatmg pipes17, discharging and distributing the milkfor cream adjacent to the innercooled wall of the vat. This distribution is intensifed when the shaft14 is revolved, due to the vaction of the centrifugal force and furtheracting to brin the milk or cream to a sudden chill, dueto t emotion setup in the same b reason ofthe movement of thevpaddle 1 9. j T e velocity,of this motion is controlled by adjusting the paddle' radially 'of .thevat -inwardly orv outwardly as `less or greater.
